PHENIX Technologies PATTR-3D Three Phase Transformer Ratio Tester

The PATTR-3D ratio meter is a high precision instrument, designed to measure turn ratios, phase displacements, excitation currents of single phase and three phase power, distribution and instrument transformers in compliance with IEEE C57.12.90 and IEC 60076 standards.

FEATURES
With its real 3-phase test circuit, the PATTR-3D can address complex ratio measurements of Phase- Shifting/ Regulating or irregular vector group type transformers, otherwise impossible to achieve with conventional ratio meters. Zigzag type transformer testing is very easy and will not require the
installation of jumpers or the use of relay matrix circuits. The single or real 3 phase voltage output
up to 275 V contributes to higher magnetization currents and therefore stronger flux for better signal reflection on secondary and/or tertiary windings allowing more accurate results. The PATTR-3D
phase displacement measurements enables for simple detection of the transformer vector group.

Ease of Use
With PATTR-3D’s intuitive menus, high contrast touch screen, convenient
graphical test representation, highest test voltage on the market, long and flexible
multipurpose test leads configuration, real 3-phase output, the widest range of applicable
transformer types, it has never been so simple and easy to achieve high accuracy Transformer Turn Ratio
measurements.
